Hi
I am new to QT and I have developed an applcation in QT 4.2 using GraphicsView.
I am showing 15K > rectangles(using drawEllipse) and almost 30K line between them. But zoom in/out is very slow, loading time is also too slow.
1. How to improve performance.?
2. How to use QTherad to plot/add ellipse items simulantenously in GraphicsScene. ???
3. I am doing on Windows using Microsoft Visula Studio 2003 So how to do profiling ???
Please help me
